Installation
FluidCAD is a JavaScript library for building parametric 3D models with code. You write .fluid.js files, and FluidCAD renders them in a live 3D viewport that updates as you type.
Editor Setup
FluidCAD works with any text editor. It ships official extensions for VS Code and Neovim, and a CLI for everything else. All three options give you the same live 3D viewport — pick whichever fits your workflow.
Your First Model
In this tutorial you'll build a rounded box with a circular pocket cut from the top. Along the way you'll learn the core workflow: sketch → extrude → modify.
